If you are a city innovator thinking about deploying sensors for crowd monitoring, this toolkit is a step by step guide that will help you on your journey.

Societal values guide difficult decisions government innovators need to make when thinking about using sensors for crowd monitoring.  Working with the City of Amsterdam we have created a six step process to help you on your way.  This toolkit was designed to help inform you about important considerations based on our experience and help you navigate the dilemmas you may encounter.

Workshop 1 – Quickscan

The Decision Canvas:

Much like the familiar Business Model Canvas, the RST Decision Canvas was designed to help you and your stakeholders get a comprehensive overview of Responsible and Ethical Sensing projects. Co-created with the input of several experts and field tested with practical projects, the Decision Canvas is a proven tool to get you started.

Workshop 2 – Deep Dive

Identify Attention Points:

After the Decision Canvas uncovers potential dilemmas as stakeholders discuss essential questions for each stage of the six-step-process, We have identified the need to move forward with “attention points”. These become the main topic for a productive workshop where we guide the team to explore paths to resolve these dilemmas with “action points”.

Workshop 3 – Roadmapping

Define Action Points:

It can be difficult to implement these tools on your own.  CITIXL has conducted workshops with dozens of municipal organisations from around the world and, since the Coronavirus, we have successfully created online interactive workshops using a combination of Zoom and Miro Board for a productive and engaging experience.  Sign up, tell us what you need and we will help you get started.
